Mysterious Bottom Bracket Wobblies

I recently detected a wee bit of play in my Hope Bottom Bracket (with RaceFace Evolve XC crankset), so took it to bits, replaced the bearings with new ones, lo and behold, I've still got the same amount of play when I grab the crank arms and give them a shoogie.

I'm certain that everything, including spacers, is fitted correctly and tightly. Any ideas?

What's this 10mm Hex Puller Cap you're on about? All I've got is the 8mm crank bolt. Have I been missing something all these years? Actually, before everyone who knows me posts up pointing out the obvious, maybe I should qualify that last bit. Have I been missing something from my bottom bracket setup all these years?

Don't some Raceface cranks have some sort of confusing extra spacer bullshit involved? Folks I know who have them are always fannying around with spacers trying to stop them wobbling. It's god's way of reminding you that you should have bought Shimano.

On the Raceface cranks if you look at the right hand crank there is an 8mm crank bolt that tightens the rh crank into the axle. There is also a 10mm crank puller cap that sits around the 8mm bolt so to tighten the 8mm bolt you go through the 10mm opening.
